Objective Using high-resolution 3.0T MRI imaging technology,the anatomy and imaging manifestations of the tendon and ligament injury in the hindfoot were studied,providing anatomical and imaging evidence for the diagnosis and treatment of hindfoot injury.Methods From June 2015 to September 2021,65 patients with hind foot tendon and ligament injuries confirmed by surgery or clinical follow-up and 15 healthy volunteers(30 feet)were retrospectively analyzed.All pa-tients with hindfoot injury andvolunteers underwent coronal,sagittal,and axial MRI T1 WI and PD-FS sequence examinations of the middle and hind feet.To analyze the normal anatomy and MRI findings of the tendon and ligament of the hindfoot after injury.Results The tendons and ligaments of the hind foot of 15 healthy volunteers(30 feet)showed uniform strip or lin-ear low signal,among which the peroneus longus tendon,peroneus brevis tendon,and achilles tendon showed uniform strip low signal,while the calcaneocuboid ligament and plantar fascia showed linear low signal.There were 65 cases of hind foot tendon and ligament injury,including10 cases(10/65)of peroneal tendon injury,17 cases of peroneal brevis tendon inju-ry,10 cases of calcaneocuboid ligament injury,12 cases of plantar fasciitis,and 16 cases of Achilles tendon injury.The T1 WI sequence of the injured tendon and ligament showed discontinuous,thickened,and blurred fibers,while the PD-FS se-quence showed uneven high signal in the traveling area of the tendon and ligament,fluid accumulation in the tendon sheath,and partial tears showed discontinuous,thickened fibers.Complete tears manifest as fiber disruption and retraction,with the fiber structure at the broken end disappearing,filled with fluid,and surrounding soft tissue edema.Conclusion High reso-lution 3.0T MRI can clearly display the fine anatomical structure of the hind foot tendon and ligament and the imaging man-ifestations of the injury,which has important clinical application value for the early diagnosis and treatment of hind foot ten-don and ligament injury.
